The Democratic National Convention has signaled from the start an unapologetic, and at times, confrontational, liberalism, marked by details like the presence of reproductive rights activist Sandra Fluke.

A video that showed on the convention floor Tuesday night offered an unusually direct embrace of the role of government in American life: "Government," says the narrator, "is the only thing that we all belong to."

UPDATE: An Obama aide emails that the Charlotte host committee, not the Obama campaign, produced the video:

“The video in question was produced and paid for by the host committee of the city of Charlotte. It’s neither an OFA nor a DNC video, despite what the Romney campaign is claiming. It's time for them to find a new target for their faux outrage."

And Dan Murrey, the executive director of the Charlotte in 2012 Host Committee, said in an emailed statement:

The “Welcome to Charlotte” video was solely produced and paid for by the Host Committee’s New American City Fund, which promotes the city of Charlotte and welcomes our guests. The intent of this video was to tell the story of this region and it is completely unaffiliated with the Obama campaign or the Democratic National Committee.
